See how your money grows over time with compounding
Albert Einstein allegedly called compound interest the "eighth wonder of the world." Whether or not he actually said it, the math backs up the sentiment. Compounding is the process where your investment earnings generate their own earnings, creating exponential growth over time.
A = P(1 + r/n)^(nt) + PMT × ((1 + r/n)^(nt) - 1) / (r/n)
Where: A = future value, P = principal, r = annual rate, n = compounding frequency, t = time in years, PMT = periodic contribution.
When you reinvest rental income — whether by paying down mortgages faster, acquiring additional properties, or investing in index funds — you're harnessing compound growth. A landlord who reinvests $500/month of rental cash flow at 8% will have over $294,000 in 20 years, having contributed only $120,000 out of pocket.
The key variables that accelerate compounding: time (start early), rate (invest wisely), and contributions (reinvest consistently). Even small increases in any of these dramatically change the outcome over decades.
